Republicans pass tax cuts which increase the burden on the poor and the middle class for the benefits of the ultrarich (not the majority of their voters).
They destroy government programs that benefit the majority of the population - health care, antitrust enforcement, free tax filing, environmental protections, tax audits of rich tax cheats.
They oppose any programs which provide benefits to the public - broadband standards, net neutrality, social services, cybersecurity, weather satellites, libraries, public schools, so many more.
The vast majority of their voters are hurt by these policies and are quite literally voting against their interests.
ASOF now, your comment is no longer flagged, and I just upvoted it, so maybe it will recover.
I wouldn't underestimate the role of bots, or bot assisted socks, rather than the HN community. You last sentence just sounds like sour grapes in this context.
